Start By: a. Remove the Drive Shaft. Refer to Disassembly and Assembly Manual, "Drive Shaft - Remove and Install". b. Remove the Piston Motor. Refer to Disassembly and Assembly Manual, "Piston Motor (Hydrostatic) - Remove".

NOTICE Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.

Dispose of all fluids according to local regulations and mandates.

Personal injury can result from hydraulic oil pressure and hot oil.

Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.

Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

1. Drain the transfer drive oil into a suitable container. The capacity of the transfer drive is 1.3 L (0.3 US gal).
